What's new in this version:

Reworking of the upload code and better IO handling, which allows eMule to more efficiently handle high bandwidth lines, utilizing the full upload capacity (which means others can download faster).

Optimized internal handling of the AICH hashes, the replacement of the (defunct) Filedonkey search option with the ContentDB and the update of used libraries, like miniupnpc making UPnP compatible with more devices.
